CHEVY CHASE, MD — For years, Travel Channel's hit original series "Ghost Adventures" has been going where most fear to tread: the earth's most haunted locations. Lead investigator Zak Bagans, along with co-investigators Nick Groff and Aaron Goodwin, explore unexplained paranormal activity all over the world in their never-ending quest to understand ghostly phenomena. The team heads out on their latest journey and an all-new season beginning Friday, August 16 at 9:00 p.m. ET/PT. With thirteen hour-long episodes, season eight travels to the most mysterious and disturbing places to date and features the show's landmark 100th episode. Celebrating this milestone is the one-hour retrospective special, "Ghost Adventures: Up Close & Personal," premiering on Friday, September 27 at 9:00 p.m. ET/PT which will showcase 100 of the show's most unforgettable moments. The milestone 100th episode premieres on Friday, October 4 at 9:00 p.m. ET/PT (location TBA).

Each episode of "Ghost Adventures" follows Bagans, Groff and Goodwin as they work to uncover the paranormal mysteries that lie within a haunted location. After piecing together the haunted history of each site, the team then holds a dusk-to-dawn "lockdown" in an effort to obtain physical evidence of the paranormal and discover the truth.

"For Nick, Aaron and I, each investigation we do is personal," said Zak Bagans, lead investigator. "We are on the front lines, often with malevolent spirits, working to uncover the truths behind the paranormal and understand the secrets those who have gone before us hold. Each lockdown is rife with challenges, both physically and mentally, but we accept them; we've dedicated our lives to understanding, educating and discovering a world that is perhaps one of the greatest mysteries of all time."

In the season eight premiere, the group heads deep into the Nevada desert to investigate the 100-year-old Pioneer Saloon. The saloon is full of mysterious paranormal activity, ranging from full body apparitions to disembodied voices and plumes of cigarette smoke manifesting out of thin air. As the team digs deeper in the location's history, they discover that not only is it situated near the site of a 1942 plane crash in which actress and wife of Clark Gable — Carole Lombard — was killed. It's also where notorious card cheat Paul Coski was brutally murdered during his final card game. As the trio works to solve the mystery behind this den of doom, they capture startling evidence during their frightening lockdown.

In addition, this season will also feature a special two-hour Halloween episode that takes viewers to Transylvania, where the team will explore the truth behind the legend of Count Dracula, as they investigate the most terrifying haunted castles in this intriguing and historical Romanian province. Other lockdown locations include the 150-year-old Black Swan Inn in San Antonio, Texas; the Tuolumne General Hospital in the old mining town of Sonora, California; the notoriously violent Missouri State Penitentiary in Jefferson City, Missouri; the Yost Theater and Ritz Hotel in Santa Ana, California; a haunted century-old Victorian Mansion just outside of Boston, and more.

Leading up to its 100th episode, the "Ghost Adventures" team looks back on 100 of their most unforgettable moments with the one-hour special, "Ghost Adventures: Up Close & Personal." Divided across ten different categories — including funniest, scariest, riskiest, most disturbing locations and best star cameos, to name a few — each of the top picks are chosen by Bagans, Groff and Goodwin, along with fans who voted in five of the categories earlier this summer online.
